Contribution of coping style to the association between illness uncertainty and demoralisation in patients with breast cancer: a cross-sectional mediation analysis

Abstract

ObjectiveDemoralisation is a common psychological issue in patients with cancer and aggravates depression, reduces the quality of life and even causes suicidal ideation. There is a lack of knowledge about illness uncertainty, coping style and demoralisation in patients with breast cancer. The current study explored the relationship between illness uncertainty and demoralisation among those patients, as well as the potential mediating role of coping style.DesignA cross-sectional study.SettingParticipants were recruited from the Breast Tumor Center in a tertiary hospital in Shijiazhuang, Hebei province.ParticipantsA total of 211 patients with breast cancer completed the survey.Outcome measuresA total of 211 patients with breast cancer completed the Mishel’s Uncertainty in Illness Scale, Trait Coping Style Questionnaire and the Mandarin version of Demoralization Scale (DS-MV).ResultsOf the patients, 47.40% exhibited symptoms of demoralisation (DS-MV>30), and the mean of demoralisation score was (29.55±13.21). The results demonstrated that illness uncertainty and negative coping styles were positively related to demoralisation (p<0.001), while active coping styles were negatively related to demoralisation (p<0.001). Importantly, coping styles could partially mediate the relationship between illness uncertainty and demoralisation (p<0.01).ConclusionOur study illustrated that illness uncertainty was associated with demoralisation in patients with breast cancer, and coping style acted as a mediator in this relationship. The findings highlighted the critical role of reducing negative coping styles to the early prevention and efficient treatment of demoralisation among those patients.
